CASTER-COLTER.

SPECIFICATION forming part of Letters Patent No. 324,482, dated August 18,71885.

(No model.)

To a/ZZ whom, it may concern: l

Beit known that I, WILLIAM S. BATES, a citizen of the United States, residing at Alton, in the county of Madison and State of Illinois, have invented a new and useful Improvement in Caster-Colters, of which the following is a specification.

My invention relates to castercolters in which the yoke is limited in its play, and it consists in certain improvements of construction, which will rst be described in the specification, and afterward pointed out in the claim. Y

Referring to the drawings, like letters refer to like parts in all the figures, in which- Figure l is a side elevation Viewof my im-V proved caster-colter, showing a section of the plow-beam A, and the'colter-standard B, to which the yoke Gis attached. Fig. 2 is a top view of same, showing the colter-blade D in a liue parallel with the beam, with dotted lines showing the limited play of the blade. Fig. 3 is a view same as Fig. 2, with the crank-standard B turned, moving the blade D outward from the beam A. Fig. 4 is a sectional View, enlarged, showing the bottom end of the standard B, the spring key or pin a, and clutch-washer J. Fig. 5 is a perspective View, enlarged, of the clutchwasher J, showing its top end provided with a series of clutch-teeth, b, and its bottom end provided with a stop, n. Fig. 6 is a bottom end view, enlarged, of the hub end h of the yoke C, showing a like series of clutch-teeth, c, same asin the clutch-washer J.

The colter is provided with the usual blade, D, yoke C, and crank-standard B, all of usual construction, except as modified to be used with my improvements.

In my improvements the bottom end of the hub h of the yoke C is provided with a series of clutch-teeth, c, to clutch with like teeth in the washer J.

J represents the clutch-washer,` having its top end provided with the series of clutchteeth b, to clutch with the teeth c upon the yoke C, and with the stop n, to strike against the pin a, to limit the play of the yoke and blade, as will be understood by the drawings.

In operation it will be observed that the washer J may be moved into as many positions as it has clutch-teeth, by which the stop n may be moved into any desired position relative to the yoke and blade. The standard B is inserted through the hub of the yoke and the washer, and the pin a, inserted through a perforation in the end of the standard, secures the yoke and washer to the standard in any desired position, all of which will be understood by the drawings.

The blade may be limited in its play or vibration to an equal distance each side of the center line, as shown in Fig. '2, and in a changed position of the crank of the standard shown in Fig. 3. The washer may also be changed in its position, so that the relative yposition and play of the yoke and blade remain unchanged as to parallel line of draft, as will be understood by the drawings.

I am aware that it is not new to move and adjust the yoke upon the standard; also not new to limit the vibration-play of the-colter. Such I do not broadly claim.

Having thus set forth my invention,I claim- In a caster-colter having the cranked standard constructed with an offset, as shown, the yoke C, having the perforated hub h, provided with a series of clutch-teeth, the washer J provided with clutchteeth adapted to engage with the clutch-teeth upon the said hub, and the said hub and washer pivotally attached to the bottom end of the said standard in a manner permitting a limited lateral vibration-play of the colter-blade, all substantially as and for the purpose set forth.
